"The postpartum depression I have been experiencing has impacted every aspect of my life," she wrote. "Rather than stay stuck due to unhealthy coping mechanisms I have chosen to take time to reflect holistically on my health and life. Wish me luck!"

Panettiere had previously entered treatment for the condition back in October 2015, following the birth of her daughter, Kaya, in December 2014. A representative for the 26-year-old said at the time that she was "voluntarily seeking professional help at a treatment center as she is currently battling postpartum depression."

In an odd coincidence, Panettiere's character on the ABC drama "Nashville" (which was just cancelled) also struggled with postpartum depression, and entered rehab. Panettiere then took some time off from the program while she herself sought treatment, and her absence was written into the series.

While discussing that storyline, the actress said in a September 2015 interview on "Live! With Kelly and Michael" that she could "very much relate" to her character's PPD.

"It's something a lot of women experience," Panettiere said at the time. "When [you're told] about postpartum depression you think it's 'I feel negative feelings towards my child, I want to injure or hurt my child' — I've never, ever had those feelings. Some women do. But you don't realize how broad of a spectrum you can really experience that on. It's something that needs to be talked about. Women need to know that they're not alone, and that it does heal."

We applaud Panettiere for speaking out about such an important issue, and wish her all the best in her continued recovery.
